Actually, U of M uses a strange formula to fugure out their tuition reimbursement. They pay a percentage of what full time in state tuition would be at U of M. They pay the same amount regardless of what school you attend. Then it is changed based on your appointment fraction. It works out to about $800 a semester if you are a 40 hour a week employee. I have a 36 hour appointment, so mine worked out to $776.25 this semester and I got the maximum allowed.
I was just hired for a part time position at St. Joe's. Included with the benefits packet was info on tuition reimbursement. Part time employees can receive up to $800.00 per year for tuition reimbursement and up to $1200.00 per year for full time employees. Hope this helps.
